BH3514BFV
BH3514BFV is RF AMplifier manufactured by RF Monolithics.
Description
The BH3514BFV is a RF amplifier for Car CD players that has a built-in equalizer circuit (EQ). The equalizer circuit is applied to x1, x2 and x4 speeds. The equalizer circuit has improved characteristics, which will enhance the overall performance during mobile jitter conditions. Boost quantity and phase characteristics can also be controlled. Gain up SW for CD-R/RW is incorporated and is available for multi-reads. LD voltage can be switched in 3-steps. This RF amplifier is available for each pick. Features
1) For CD (x1, x2, x4 speeds) 2) Multi-read type (built-in gain up SW for CD-R/RW) 3) LD voltage changeable in 3 steps 4) Built-in electronic volume for control tracking and focus 5) Built-in EQ circuit has group delay characteristics of an improved type 6) Boost quantity and phase characteristic can be controlled Dimension (Unit : mm)
